30	<h2>New-Gauge-Boson Processes</h2>
31
32	This page contains the production of new <i>Z'^0</i> and
33	<i>W'^+-</i> gauge bosons, e.g. within the context of a new
34	<i>U(1)</i> or <i>SU(2)</i> gauge group, and also a
35	(rather speculative) horizontal gauge boson <i>R^0</i>.
36	Left-right-symmetry scenarios also contain new gauge bosons,
37	but are described
38	<?php $filepath = $_GET["filepath"];
39	echo "<a href='LeftRightSymmetryProcesses.php?filepath=".$filepath."' target='page'>";?>separately</a>.

41	<h3><i>Z'^0</i></h3>
42
43	This group only contains one subprocess, with the full
44	<i>gamma^*/Z^0/Z'^0</i> interference structure for couplings
45	to fermion pairs. It is possible to pick only a subset, e.g, only
46	the pure <i>Z'^0</i> piece. No higher-order processes are
47	available explicitly, but the ISR showers contain automatic
48	matching to the <i>Z'^0</i> + 1 jet matrix elements, as for
49	the corresponding <i>gamma^*/Z^0</i> process.

75
76	<p/>
77	The couplings of the <i>Z'^0</i> to quarks and leptons can
78	either be assumed universal, i.e. generation-independent, or not.
79	In the former case eight numbers parametrize the vector and axial
80	couplings of down-type quarks, up-type quarks, leptons and neutrinos,
81	respectively. Depending on your assumed neutrino nature you may
82	want to restrict your freedom in that sector, but no limitations
83	are enforced by the program. The default corresponds to the same
84	couplings as that of the Standard Model <i>Z^0</i>, with axial
85	couplings <i>a_f = +-1</i> and vector couplings
86	<i>v_f = a_f - 4 e_f sin^2(theta_W)</i>, with
87	<i>sin^2(theta_W) = 0.23</i>. Without universality
88	the same eight numbers have to be set separately also for the
89	second and the third generation. The choice of fixed axial and
90	vector couplings implies a resonance width that increases linearly
91	with the <i>Z'^0</i> mass.
92
93	<p/>
94	By a suitable choice of the parameters, it is possible to simulate
95	just about any imaginable <i>Z'^0</i> scenario, with full
96	interference effects in cross sections and decay angular
97	distributions and generation-dependent couplings; the default values
98	should mainly be viewed as placeholders. The conversion
99	from the coupling conventions in a set of different <i>Z'^0</i>
100	models in the literature to those used in PYTHIA is described by
101	<a href="http://www.hep.uiuc.edu/home/catutza/nota12.ps">C.

107	If on then you need only set the first-generation couplings
108	below, and these are automatically also used for the second and
109	third generation. If off, then couplings can be chosen separately
110	for each generation.

216
217	<p/>
218	The coupling to the decay channel <i>Z'^0 -> W^+ W^-</i> is
219	more model-dependent. By default it is therefore off, but can be
220	switched on as follows. Furthermore, we have left some amount of
221	freedom in the choice of decay angular correlations in this
222	channel, but obviously alternative shapes could be imagined.

225	the coupling <i>Z'^0 -> W^+ W^-</i> is taken to be this number
226	times <i>m_W^2 / m_Z'^2</i> times the <i>Z^0 -> W^+ W^-</i>
227	coupling. Thus a unit value corresponds to the
228	<i>Z^0 -> W^+ W^-</i> coupling, scaled down by a factor
229	<i>m_W^2 / m_Z'^2</i>, and gives a <i>Z'^0</i> partial
230	width into this channel that again increases linearly. If you
231	cancel this behaviour, by letting <code>Zprime:coup2WW</code> be
232	proportional to <i>m_Z'^2 / m_W^2</i>, you instead obtain a
233	partial width that goes like the fifth power of the <i>Z'^0</i>
234	mass. These two extremes correspond to the "extended gauge model"
235	and the "reference model", respectively, of [<a href="Bibliography.php" target="page">Alt89</a>].
236	Note that this channel only includes the pure <i>Z'</i> part,
237	while <i>f fbar -> gamma^/Z^0 -> W^+ W^-</i> is available
238	as a separate electroweak process.
239
240
241	<br/><br/><table><tr><td><strong>Zprime:anglesWW </td><td></td><td> <input type="text" name="29" value="0." size="20"/>   (<code>default = <strong>0.</strong></code>; <code>minimum = 0.</code>; <code>maximum = 1.</code>)</td></tr></table>
242	in the decay chain <i>Z'^0 -> W^+ W^- ->f_1 fbar_2 f_3 fbar_4</i>
243	the decay angular distributions is taken to be a mixture of two
244	possible shapes. This parameter gives the fraction that is distributed
245	as in Higgs <i>h^0 -> W^+ W^-</i> (longitudinal bosons),
246	with the remainder (by default all) is taken to be the same as for
247	<i>Z^0 -> W^+ W^-</i> (a mixture of transverse and longitudinal
248	bosons).
249
250
251	<p/>
252	A massive <i>Z'^0</i> is also likely to decay into Higgses
253	and potentially into other now unknown particles. Such possibilities
254	clearly are quite model-dependent, and have not been included
255	for now.
256
257	<h3><i>W'^+-</i></h3>
258
259	The <i>W'^+-</i> implementation is less ambitious than the
260	<i>Z'^0</i>. Specifically, while indirect detection of a
261	<i>Z'^0</i> through its interference contribution is
262	a possible discovery channel in lepton colliders, there is no
263	equally compelling case for <i>W^+-/W'^+-</i> interference
264	effects being of importance for discovery, and such interference
265	has therefore not been implemented for now. Related to this, a
266	<i>Z'^0</i> could appear on its own in a new <i>U(1)</i> group,
267	while <i>W'^+-</i> would have to sit in a <i>SU(2)</i> group
268	and thus have a <i>Z'^0</i> partner that is likely to be found
269	first. Only one process is implemented but, like for the
270	<i>W^+-</i>, the ISR showers contain automatic matching to the
271	<i>W'^+-</i> + 1 jet matrix elements.

279
280	<p/>
281	The couplings of the <i>W'^+-</i> are here assumed universal,
282	i.e. the same for all generations. One may set vector and axial
283	couplings freely, separately for the <i>q qbar'</i> and the
284	<i>l nu_l</i> decay channels. The defaults correspond to the
285	<i>V - A</i> structure and normalization of the Standard Model
286	<i>W^+-</i>, but can be changed to simulate a wide selection
287	of models. One limitation is that, for simplicity, the same
288	Cabibbo--Kobayashi--Maskawa quark mixing matrix is assumed as for
289	the standard <i>W^+-</i>. Depending on your assumed neutrino
290	nature you may want to restrict your freedom in the lepton sector,
291	but no limitations are enforced by the program.

333	in the decay chain <i>W'^+- -> W^+- Z^0 ->f_1 fbar_2 f_3 fbar_4</i>

346	for now.
347
348	<h3><i>R^0</i></h3>
349
350	The <i>R^0</i> boson (particle code 41) represents one possible
351	scenario for a horizontal gauge boson, i.e. a gauge boson
352	that couples between the generations, inducing processes like
353	<i>s dbar -> R^0 -> mu^- e^+</i>. Experimental limits on
354	flavour-changing neutral currents forces such a boson to be fairly
355	heavy. In spite of being neutral the antiparticle is distinct from
356	the particle: one carries a net positive generation number and
357	the other a negative one. This particular model has no new
358	parameters beyond the <i>R^0</i> mass. Decays are assumed isotropic.
359	For further details see [<a href="Bibliography.php" target="page">Ben85</a>].
